The hand tool 6 comprises the handle structure, and the handle structure is arranged on the equipment main body of the hand tool 6.

[0050] In order to achieve the above object, the technical scheme provided by an embodiment of the utility model is as follows:

[0051] As shown in Figures 1 to 10 The utility model provides a handle structure. As shown in Figure 1 And Figure 5 The handle structure is composed of multiple components. The handle structure comprises a handle assembly 1, a gear shifting piece 2 and a driving assembly 3. The handle assembly 1 is arranged on the tool to be installed in a position-adjustable manner, so that the handle assembly 1 has multiple gear position positions relative to the tool to be installed; a limiting piece 11 is arranged on the handle assembly 1. The gear shifting piece 2 is arranged on the tool to be installed; the gear shifting piece 2 is in limiting cooperation with the limiting piece 11, so that the handle assembly 1 is selectively limited at a gear position position. The driving assembly 3 is arranged on the handle assembly 1, and the driving assembly 3 is drivingly connected with the limiting piece 11, so as to drive the limiting piece 11 to move to a disengagement position away from the gear shifting piece 2 or a limiting position limited with the gear shifting piece 2 by operating the driving assembly 3, so as to adjust the gear position position of the handle assembly 1.

[0052] The handle structure provided by the embodiment of the utility model not only enables the handle assembly 1 to be adjusted in position relative to the tool to be installed, so as to adjust the height or angle of the handle assembly 1 according to the user's own needs or the specific scene of tool use. By integrating the driving assembly 3 on the handle assembly 1, the user can directly drive the limiting piece 11 to move by operating the driving assembly 3, without using additional tools or moving to other parts of the tool for adjustment, thereby realizing quick and tool-free gear adjustment and improving the convenience and efficiency of operation. In addition, by arranging the gear shifting piece 2, limiting the cooperation between the limiting piece 11 and the gear shifting piece 2, and directly driving the driving assembly 3, the gear position change caused by accidental touch during use can be effectively prevented, and convenient gear position change can be realized when needed, thereby ensuring the safety of operation and the stability of tool use. Therefore, the handle structure provided by the embodiment can solve the problem that the handle structure of the hand tool in the prior art is not convenient for quick gear adjustment.

[0053] Specifically, the tool to be installed is a garden tool. Specifically, the tool to be installed is the equipment main body of the hand tool 6.

[0054] Specifically, the push tool 6 can be a lawnmower.

[0055] Specifically, the grip assembly 1 includes a connecting rod 12 and a grip 13 connected to each other. The connecting rod 12 is used to connect with the tool to be installed, and the grip 13 is used to manipulate and drive the movement of the connecting rod 12.

[0056] Specifically, the position of the grip assembly 1 relative to the tool to be installed is adjustable. The grip assembly 1 has multiple different positions relative to the tool to be installed. Each position corresponds to a relative position of the grip assembly 1 and the tool to be installed, in order to meet different operational needs.

[0057] Specifically, the gear positions include at least a first gear, a second gear, a third gear, and a folding gear. When the grip assembly 1 is in the first gear, the height of the grip 13 relative to the ground is greater than when the grip assembly 1 is in the second gear; when the grip assembly 1 is in the second gear, the height of the grip 13 relative to the ground is greater than when the grip assembly 1 is in the third gear. When the grip assembly 1 is in the folding gear, the grip assembly 1 is stacked on the main body of the tool to be installed, reducing the overall space occupied by the tool. When the grip assembly 1 is in the first, second, or third gear, the grip assembly 1 is unfolded relative to the main body of the tool to be installed, with the grip 13 located on one side of the main body for easy gripping by the operator.

[0058] Specifically, when it is necessary to switch the current gear position of the grip assembly 1, the operating drive assembly 3 drives the limiting member 11, which is in the limiting position, to move to the disengaged position. Then, the operating grip assembly 1 moves to the disengaged position corresponding to another gear position, and the operating drive assembly 3 further drives the limiting member 11 to move to the limiting position corresponding to another gear position, thereby completing the gear position switch.

[0059] In this application, the shift component 2 is provided with a limiting part 20 that cooperates with the limiting component 11 to achieve precise positioning and switching of different gear positions.

[0060] In one specific embodiment, there are multiple limiting parts 20, so as to adjust the gear position of the grip assembly 1 by moving the limiting member 11 to the limiting position corresponding to each limiting part 20.

[0061] In this specific embodiment, the limiting part 20 can be a plurality of limiting grooves, and the limiting member 11 is a limiting protrusion adapted to the limiting groove.

[0062] In this specific embodiment, the limiting part 20 can be a plurality of limiting protrusions, the limiting member 11 is a limiting piece, and the limiting piece is provided with a limiting groove that matches the limiting protrusion.

[0063] In an embodiment not shown, the limit member 11 is in plurality, and the gear position of the handlebar assembly 1 is adjusted by moving each limit member 11 to the limit position corresponding to the limit portion 20.

[0064] In this embodiment, the limit member 11 is in plurality of limit protrusions, and the limit portion 20 is in plurality of limit grooves corresponding to the limit protrusions.

[0065] In this embodiment, the limit member 11 is in plurality of limit grooves, and the limit portion 20 is in plurality of limit protrusions corresponding to the limit grooves.

[0066] As shown in Figure 1 and Figure 5 , the handlebar assembly 1 has a rotation shaft 142, and the handlebar assembly 1 is arranged rotatably around the rotation shaft 142 on the tool to be installed; the shift member 2 is provided with a plurality of gear slots 21, and the plurality of gear slots 21 are arranged in sequence along the rotation track of the handlebar assembly 1, and each gear slot 21 is arranged for limit cooperation with the limit member 11. In this way, the rotatable design of the handlebar assembly 1 around the rotation shaft 142 and the plurality of gear slots 21 on the shift member 2 enable the user to rotate the handlebar assembly 1 to adjust the handlebar assembly 1 to a plurality of preset gear positions, meet the use requirements in different scenarios, and improve the flexibility and adaptability of the tool.

[0067] Specifically, the plurality of gear slots 21 includes a first gear slot 212, a second gear slot 213, a third gear slot 214, and a folding gear slot 211. The first gear slot 212 corresponds to a first gear, the second gear slot 213 corresponds to a second gear, the third gear slot 214 corresponds to a third gear, and the folding gear slot 211 corresponds to a folding gear. When the limit member 11 is limited in the first gear slot 212, the handlebar assembly 1 is in the first gear. When the limit member 11 is limited in the second gear slot 213, the handlebar assembly 1 is in the second gear. When the limit member 11 is limited in the third gear slot 214, the handlebar assembly 1 is in the third gear. When the limit member 11 is limited in the folding gear slot 211, the handlebar assembly 1 is in the folding gear.

[0068] Specifically, as shown in Figure 3 and Figure 6 , the limit member 11 is a rod-shaped member, the diameter of the cross section of the limit member 11 is D, and the depth of each gear slot 21 is h; wherein: 3h≥2D. In this way, since the cooperation relationship between the diameter D of the cross section of the limit member 11 and the depth h of the gear slot 21 is 3h≥2D, it is ensured that when the limit member 11 enters the gear slot 21, it can be effectively supported and limited by the side wall of the slot, preventing the limit member 11 from slipping out or loosening due to external force during use, thereby enhancing the stability and locking effect of the handlebar assembly 1 in a specific gear position.

[0069] Specifically, as shown inFigure 3 and Figure 6 As shown, the limiting member 11 is a rod-shaped member with a cross-sectional diameter of D, and the width of each gear slot 21 is d; where D≤d≤1.5D. This design, where the width of the gear slot 21 is slightly greater than or equal to the diameter of the limiting member 11, ensures the stability of the limiting member 11 within the slot while allowing the user to easily switch the limiting member 11 from one gear slot 21 to another, achieving a balance between stability and ease of operation.

[0070] Specifically, the limiting component 11 is a limiting pin.

[0071] In this application, the grip assembly 1 includes a connecting rod 12 for connecting to the tool to be installed; the drive assembly 3 includes a drive member 31, which is disposed on the connecting rod 12; a limiting member 11 is disposed on the connecting rod 12, one end of the drive member 31 is fixedly connected to the limiting member 11, and the drive member 31 is movably disposed along the extension direction of the connecting rod 12 to drive the limiting member 11 to disengage from the shift member 2.

[0072] Since the drive component 31 is mounted on the connecting rod 12, the integration of the drive component 31 and the connecting rod 12 makes the drive assembly 3 directly become part of the grip assembly 1. Users can control the limit component 11 directly by moving the drive component 31 without any additional steps during operation, which enhances the continuity and convenience of operation.

[0073] In one specific embodiment, such as Figure 5 As shown, the connecting rod 12 forms a receiving cavity 121, and the driving component 31 is disposed in the receiving cavity 121 to improve the integration of the driving component 31 and the connecting rod 12 and improve the overall structural compactness.

[0074] In an embodiment not shown, the drive element 31 is disposed on the outer wall of the connecting rod 12 to facilitate the inspection and maintenance of the drive element 31.

[0075] Specifically, the end of the drive member 31 away from the limit member 11 can be driven manually or by an electric device to move the drive member 31 along the extension direction of the connecting rod 12, thereby driving the limit member 11 to move along the extension direction of the connecting rod 12, so as to make the limit member 11 disengage from the gear slot 21 with less effort.

[0076] like Figure 5 As shown, the driving component 31 is a cable component, one end of which is connected to the limiting component 11, and the other end is movably disposed along the extension direction of the connecting rod 12.

[0077] In an embodiment not shown, the driving member 31 is a push rod, one end of which is connected to the limiting member 11, and the other end is movably disposed along the extension direction of the connecting rod 12.

[0078] In one specific embodiment, such as Figure 6 As shown, the drive assembly 3 also includes an elastic element 32, which contacts the limiting element 11 so that after the drive assembly 31 releases the limiting element 11, the limiting element 11 returns to its limit position under the elastic action of the elastic element 32. With this configuration, the automatic reset mechanism of the elastic element 32 allows the user to complete gear adjustment without operating the drive assembly 31 to drive the limiting element 11 to the gear slot 21. The user only needs to stop operating the drive assembly 31 and wait for the limiting element 11 to enter its limit position under the elastic action. This is more labor-saving and significantly improves operating efficiency, especially in cases of continuous or rapid gear switching.

[0079] Specifically, the elastic member 32 has a fixed end 321 and a free end 322 spaced apart along the extension direction of the connecting rod 12. The fixed end 321 is fixedly disposed on the connecting rod 12, and the free end 322 is located on the side of the fixed end 321 near the limiting member 11 and is used to abut against the limiting member 11.

[0080] Specifically, the drive assembly 3 also includes a limiting block 36, which is disposed on one side of the elastic member 32 to limit the side of the elastic member 32 away from the limiting member 11.

[0081] Specifically, the elastic element 32 can be a spring, an elastic band, or an elastic washer.

[0082] In an embodiment not shown, the drive assembly 3 further includes a magnetic attractor for attracting the limiting member 11. After the drive assembly 31 releases the limiting member 11, the limiting member 11 returns to its limiting position under the magnetic force of the magnetic attractor. This simplifies the structure of the drive assembly 3, eliminating the need for complex spring installation and adjustment, thus reducing production difficulty and cost. The magnitude of the magnetic force can be precisely controlled by the type and size of the magnetic attractor, ensuring that the limiting member 11 stably returns to its limiting position upon reset.

[0083] like Figure 5 As shown, in this application, the drive assembly 3 also includes an operating member 33, which is disposed on the connecting rod 12 and located on the side of the connecting rod 12 away from the shift member 2; the operating member 33 is fixedly connected to the end of the drive member 31 away from the limiting member 11, and the operating member 33 is movably disposed along the extension direction of the connecting rod 12 so as to drive the drive member 31 to drive the limiting member 11 to disengage from the shift member 2.

[0084] Since the operating component 33 is located on the side of the connecting rod 12 away from the shifting component 2, the operating component 33 provides the user with an intuitive and easily accessible operating point, allowing the user to directly limit or disengage the limiting component 11 by operating the connecting rod 12 on the side away from the main body of the equipment, without having to move to the other end of the tool.

[0085] Specifically, the operation member 33 is connected with the driving member 31 away from one end of the limiting member 11, and the movement of the driving member 31 is driven by manually driving the operation member 33 or by an electric device, thereby driving the movement of the limiting member 11.

[0086] As shown in Figure 1 , Figure 5 and Figure 6 , the handle assembly 1 comprises connecting rods 12 for connecting with tools to be installed, and the connecting rods 12 are at least two; each connecting rod 12 is provided with a set of limiting members 11 and driving assemblies 3 matched with each other, and the shifters 2 are at least two, and the at least two shifters 2 are arranged in one-to-one correspondence with the at least two limiting members 11 on the handle assembly 1. In this way, the limiting members 11 and the driving assemblies 3 on each connecting rod 12 are independent, and then can realize multi-point synchronous or independent adjustment according to different needs, which not only can adapt to more complex use environment and operation demand, but also can significantly enhance the stability of the handle assembly 1 as a whole, especially when uneven external force is borne, the stability of the handle position can be more effectively maintained.

[0087] Specifically, the handle assembly 1 further comprises a handle 13.

[0088] In a specific embodiment, the connecting rod 12 and the handle 13 are each one, and one connecting rod 12 and one handle 13 are connected.

[0089] In a specific embodiment, the connecting rod 12 is one, and the handle 13 is two, and the two handles 13 and the one connecting rod 12 are all connected.

[0090] In a specific embodiment, the connecting rod 12 is two, and the handle 13 is two, and each connecting rod 12 is connected with each handle 13, respectively.

[0091] In a specific embodiment, the connecting rod 12 is two, and the handle 13 is four, and each connecting rod 12 is connected with two handles 13, respectively.

[0092] In a specific embodiment, the connecting rod 12 is two, and the handle assembly 1 further comprises a handle 13, the two connecting rods 12 are arranged at intervals along the extension direction of the handle 13, and the two connecting rods 12 are connected with the handle 13; each driving assembly 3 comprises a driving member 31, and each driving member 31 is drivingly connected with the corresponding limiting member 11; the driving assembly 3 further comprises an operation member 33, one end of the operation member 33 is arranged on one of the two connecting rods 12 and connected with the driving member 31 on the one of the two connecting rods 12, and the other end of the operation member 33 is arranged on the other of the two connecting rods 12 and connected with the driving member 31 on the other of the two connecting rods 12; and the operation member 33 is movably arranged along the extension direction of the two connecting rods 12.

[0093] Due to the design of two connecting rods 12 being arranged at intervals, the structural stability of the handlebar assembly 1 is stronger. Each driving assembly 3 is drivingly connected with the corresponding limiting piece 11, which means that the adjustment action on each connecting rod 12 can be independently completed, and at the same time, through the arrangement of the operating piece 33, the user can drive the driving piece 31 on both connecting rods 12 at the same time through one operation, realize the synchronous limiting or disengagement of the limiting piece 11, simplify the operation process, and improve the adjustment efficiency. The user does not need to frequently switch between different parts of the handlebar 13, but only needs to operate on one side of the handlebar 13 to complete the entire adjustment process, greatly improving the convenience of operation and user experience.

[0094] As shown in Figure 6 In the present application, the handlebar assembly 1 includes a connecting rod 12 for connecting with the tool to be installed, the connecting rod 12 has a receiving cavity 121 and a guide groove 122 communicating with the receiving cavity 121, the guide groove 122 is arranged at the outer wall of the connecting rod 12; the driving assembly 3 further includes a sliding piece 34 movably arranged in the receiving cavity 121. The limiting piece 11 is arranged on the sliding piece 34, at least part of the limiting piece 11 is arranged in the guide groove 122, and the outer edge of at least part of the limiting piece 11 protrudes from the outer wall of the connecting rod 12 to limit the cooperation with the gear shifting piece 2. In this way, the receiving cavity 121 is arranged in the connecting rod 12 for accommodating the sliding piece 34 and the limiting piece 11, so that the spatial layout of the handlebar assembly 1 is more compact, and the portability of the tool and the flexibility during operation are improved. Part of the limiting piece 11 is arranged in the guide groove 122, which ensures that the limiting piece 11 can move stably along the predetermined path under the action of the driving assembly 3, the design of the guide groove 122 limits the transverse movement of the limiting piece 11, enhances the stability and accuracy of the work of the limiting piece 11, and reduces the accidental deviation or jamming phenomenon during operation.

[0095] In an embodiment not shown in the figure, the handlebar assembly 1 includes a connecting rod 12 for connecting with the tool to be installed, and a guide rail is arranged at the outer wall of the connecting rod 12, at least part of the limiting piece 11 is guided and matched with the guide rail to guide the movement direction of the limiting piece 11 through the guide rail.

[0096] As shown in Figure 6 The handlebar assembly 1 further includes a first guide part and a second guide part 35, the first guide part is arranged on the sliding piece 34, and the second guide part 35 is arranged on the connecting rod 12 and located in the receiving cavity 121, one of the first guide part and the second guide part 35 is arranged in the extension direction of the connecting rod 12, and the first guide part and the second guide part 35 are guided and matched with each other. In this way, the accuracy and smoothness of the internal movement of the handlebar assembly 1 are improved, the friction and wear during movement are reduced, and the service life of the product is prolonged.

[0097] In a specific embodiment, one of the first guide part and the second guide part 35 is a sliding rail, and the other is a sliding block.

[0098] In an embodiment not shown in the drawings, one of the first guide part and the second guide part 35 is a sliding rod, and the other is a sliding sleeve.

[0099] In an embodiment not shown in the drawings, one of the first guide part and the second guide part 35 is a rack, and the other is a gear.

[0100] As shown in Figure 1 and Figure 2 In the present application, the handle structure further comprises a rotating member 14 connected with the handle assembly 1. The shifting member 2 is provided with a placing groove 22, and the rotating member 14 is rotatably arranged in the placing groove 22 to drive the handle assembly 1 to rotate. In this way, the handle assembly 1 can be freely rotated at multiple angles, improving the flexibility and adaptability of the handle assembly 1 in use and reducing the operation difficulty.

[0101] Specifically, the rotating member 14 is a rod-shaped structure, and the central axis of the rotating member 14 is a rotating shaft 142. The rotation of the rotating member 14 drives the handle assembly 1 to rotate around the rotating shaft 142.

[0102] Specifically, there are two connecting rods 12, and the two connecting rods 12 are respectively connected with the two ends of the rotating member 14. The rotation of the rotating member 14 drives the two connecting rods 12 to rotate around the rotating shaft 142. There are two shifting members 2, and the rotating member 14 is arranged in the placing groove 22 provided on the two shifting members 2.

[0103] Specifically, as shown in Figure 9 the handle structure further comprises a cover plate 15 for limiting and fixing the position of the rotating member 14 in the placing groove 22.

[0104] As shown in Figure 2 the shifting member 2 is provided with a plurality of gear grooves 21, and the plurality of gear grooves 21 are sequentially arranged along the rotation track of the handle assembly 1. Each gear groove 21 is used for limiting cooperation with the limiting member 11. The shifting member 2 comprises a first shifting part 23 and a second shifting part 24, and the first shifting part 23 and the second shifting part 24 are respectively located on the two sides of the placing groove 22. One of the plurality of gear grooves 21 is located on the second shifting part 24, and the other gear grooves 21 are located on the first shifting part 23. In this way, the gear grooves 21 are distributed on the first shifting part 23 and the second shifting part 24. This distributed design can provide a wider adjustment angle, avoid the mutual interference between the gear grooves 21, optimize the movement mode of the handle assembly 1, and improve the space utilization and the rationality of the overall layout.

[0105] Specifically, the gear slot 21 located on the second shifting part 24 is a folding gear slot 211, and the gear slot 21 located on the first shifting part 23 includes a first gear slot 212, a second gear slot 213, and a third gear slot 214.

[0106] As shown in Figure 1 , when the limiting part 11 is located in the first gear slot 212, the projection length of the connecting rod 12 in the horizontal direction is L1, and 850mm≤L1≤950mm.

[0107] As shown in Figure 1 , when the limiting part 11 is located in the second gear slot 213, the projection length of the connecting rod 12 in the horizontal direction is L2, and 1000mm≤L2≤1100mm.

[0108] As shown in Figure 1 , when the limiting part 11 is located in the third gear slot 214, the projection length of the connecting rod 12 in the horizontal direction is L3, and 1200mm≤L3≤1300mm.

[0109] In a specific embodiment, when the limiting part 11 is located in the first gear slot 212, the projection length of the connecting rod 12 in the horizontal direction is 900mm. When the limiting part 11 is located in the second gear slot 213, the projection length of the connecting rod 12 in the horizontal direction is 1050mm. When the limiting part 11 is located in the third gear slot 214, the projection length of the connecting rod 12 in the horizontal direction is 1200mm.

[0110] It should be noted that the projection length of the connecting rod 12 in the horizontal direction is the projection length of the distance between the center axis of the rotating part 14 and the connection between the connecting rod 12 and the handlebar 13 in the horizontal direction.

[0111] Specifically, in order to reduce the overall space occupied by the device after folding, while avoiding interference between the handlebar assembly 1 and the device main body after folding, the direction from the slot opening to the slot bottom surface of the folding gear slot 211 is horizontal.

[0112] Specifically, as shown in Figure 3 , the point farthest from the slot opening of the folding gear slot 211 on the slot bottom surface of the folding gear slot 211 is the slot bottom point 2111, and the angle between the straight line where the line between the slot bottom point 2111 and the rotation center 141 of the rotating part 14 lies and the horizontal direction is a, and 0°≤a≤5°. In this way, the handlebar assembly 1 in the folding gear position can be closer to the device main body, thereby reducing the overall space occupied by the device after folding. The specific angle of the angle a can be adjusted according to the shape of the device main body and the handlebar assembly 1.

[0113] In a specific embodiment, the straight line where the line between the slot bottom point 2111 and the rotation center 141 of the rotating part 14 lies extends along the horizontal direction.

[0114] As shown in Figure 2 , the first shifting part 23 has a first guide sliding surface 231, the first shifting part 23 forms the first guide sliding surface 231 at the outer edge of the side close to the placing groove 22, and the first guide sliding surface 231 is used to abut against the limiting piece 11. With such a configuration, it is ensured that the limiting piece 11 can stably slide along the preset track of the first guide sliding surface 231 when the handlebar assembly 1 is rotating, the accuracy during the adjustment of the handlebar assembly 1 is improved, and the stability of the contact between the limiting piece 11 and the shifting piece 2 is ensured, so that the phenomenon of accidental derailment or jamming is avoided.

[0115] Specifically, the first guide sliding surface 231 is an arc surface. In this way, the movement of the limiting piece 11 can be guided by the abutment of the first guide sliding surface 231 against the limiting piece 11 and the gravity of the limiting piece 11 itself without the need to drive the limiting piece 11.

[0116] In a specific embodiment, as shown in Figure 2 , the first shifting part 23 protrudes at the outer edge E of the side close to the placing groove 22 from the outer edge F of the side close to the placing groove 22 of the second shifting part 24. In this way, the jamming during the shifting process can be better avoided.

[0117] Since the first guide sliding surface 231 is used to abut against the limiting piece 11, when the limiting piece 11 moves from the first shifting part 23 to the second shifting part 24 along with the rotation of the connecting rod 12, the limiting piece 11 that has left the first guide sliding surface 231 will move to the position closest to the rotating piece 14 under the action of gravity without the action of external force. If the outer edge F protrudes from the outer edge E, it will cause the limiting piece 11 to be easily jammed at the placing groove 22 and interfere with the groove wall of the placing groove 22, thereby causing the jamming of the handlebar assembly 1 during the rotation process, and the user needs to exert more force on the handlebar assembly 1. When the limiting piece 11 moves from the second shifting part 24 to the first shifting part 23 along with the rotation of the connecting rod 12, due to the configuration of the first guide sliding surface 231, the limiting piece 11 can move along the arc-shaped first guide sliding surface 231 more smoothly under the abutment of the first guide sliding surface 231, thereby improving the operation experience of the user.

[0118] As shown in Figure 2 , the second shifting part 24 has an avoidance surface 241 and a second guide sliding surface 242 connected to each other.

[0119] Specifically, the second shifting part 24 forms an avoiding surface 241 on the outer edge of the side close to the placing groove 22, and the avoiding surface 241 is used for avoiding the limiting part 11. In this way, the avoiding surface 241 is arranged to allow the limiting part 11 to pass smoothly when the handlebar assembly 1 is turned to the corresponding position, without interfering or colliding with the shifting part 2, simplifying the operation process, avoiding the obstacles that may be encountered when switching gears, and improving the operation efficiency.

[0120] Specifically, the avoiding surface 241 is an arc surface; or, the avoiding surface 241 is a plane; or, the avoiding surface 241 includes an arc surface segment 2411 and a plane segment 2412.

[0121] Specifically, the second shifting part 24 forms a second guide sliding surface 242 on the outer edge of the side close to the folding gear groove 211, and the second guide sliding surface 242 is used for abutting against the limiting part 11. In this way, the accurate sliding of the limiting part 11 on the second shifting part 24 is ensured, and the stability of gear adjustment is further improved.

[0122] Specifically, the limiting point 111 is the point closest to the rotating part 14 of the limiting part 11 not subjected to the driving force of the driving assembly 3, and under the condition that the limiting part 11 is not subjected to the action of the shifting part 2, the movement track of the limiting point 111 is the limit track line 112 as the handlebar assembly 1 rotates.

[0123] Specifically, the first guide sliding surface 231 is located on the side of the limit track line 112 away from the rotating part 14 and does not exceed the limit track line 112, so as to abut against the limiting part 11.

[0124] Specifically, the avoiding surface 241 is located on the side of the limit track line 112 close to the rotating part 14 and does not exceed the limit track line 112, so as to avoid the limiting part 11.

[0125] Specifically, the second guide sliding surface 242 is located on the side of the limit track line 112 away from the rotating part 14 and does not exceed the limit track line 112, so as to abut against the limiting part 11.

[0126] In the present application, in order to enhance the structural strength, the shifting part 2 is further provided with a reinforcing rib 27.

[0127] As shown in Figure 2 and Figure 10 , the device body of the hand tool 6 is provided with a first connecting part 61 and a second connecting part 62, and the shifting part 2 is provided with a first fixing part 25 and a second fixing part 26, the first fixing part 25 is used for fixedly connecting with the first connecting part 61, and the second fixing part 26 is used for fixedly connecting with the second connecting part 62, so as to install the shifting part 2 to the device body of the hand tool 6.

[0128] Specifically, the first fixing member 25 and the second fixing member 26 are both screw structures. The first connecting part 61 and the second connecting part 62 are both nut structures or threaded hole structures.

[0129] As shown in Figure 7 and Figure 8 In the present application, the handle structure further comprises an identification member 4 and a position detection member 5. The identification member 4 is arranged on the rotating member 14, and the identification member 4 has an identification part 41. The detection end of the position detection member 5 is arranged towards the identification member 4, so as to obtain the position of the identification part 41 through the position detection member 5, to control the main machine of the tool to be installed to stop. In this way, through the cooperation of the identification member 4 and the position detection member 5, the tool main machine can adjust the stop state in real time according to the motion state of the handle assembly 1.

[0130] Specifically, the identification part 41 rotates with the rotating member 14, and when the handle assembly 1 is in the first gear, the second gear or the third gear, the identification part 41 avoids the detection end of the position detection member 5; when the handle assembly 1 is in the folding gear, the identification part 41 is towards the detection end of the position detection member 5.

[0131] Specifically, when the detection end of the position detection member 5 obtains the identification part 41, it means that the handle assembly 1 is in the folding gear, at this time, the controller of the tool to be installed controls the main machine of the tool to be installed to be in the stop state. In this way, the safety of the user is improved, when the handle assembly 1 is adjusted to the folding gear, the start of the main machine is limited, and safety accidents caused by improper operation or sudden hand release are effectively avoided.

[0132] In a specific embodiment, the identification member 4 is sleeved on the rotating member 14, and the identification member 4 has a protrusion, the protrusion forms the identification part 41, and when the protrusion rotates to the position of contacting the detection end of the position detection member 5 with the rotation of the handle assembly 1, the main machine of the tool to be installed stops. The position detection member 5 is a micro switch.

[0133] In an embodiment not shown in the figure, the identification part 41 can be an optical mark, and the position detection member 5 is an optical sensor.

[0134] In an embodiment not shown in the figure, the identification part 41 can be a magnetic mark, and the position detection member 5 is a magnetic sensor.

[0135] In an embodiment not shown in the figure, the identification part 41 can be an RFID (Radio Frequency Identification) tag. The position detection member 5 is an RFID reader.

[0136] In an embodiment not shown in the figure, the identification part 41 can be an electronic chip. The position detection member 5 is a wireless signal receiver.
